Example

Parameters of the start_context and current_context objects are given below:

x - {number} horizontal event position

y - {number} vertical event position

target - {object} the html element where the event started/ended

time - {Date object} the time of event start/end

To check whether the swipe direction is "from right to left" or "from left to right", you can calculate the difference between currentContext.x and startContext.x.
If the difference is positive, swipe movement direction was "from left to right". In case of a negative value, the direction was "from right to left".

// example of usage
webix.attachEvent("onSwipeX",function(c1,c2){if( c2.x- c1.x>0){// swipe from left to right}else{// swipe from right to left}});
